FURNACE WALL.

`.Application led April 24, 1922. Serial No. 556,195.

To all who-m, it may concern Be it known that I, MICHAEL Lieren, a citizen of the United States, residing at St. Paul, in the 'county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Furnace Walls; and I do hereby declare the following to be a full, clear, and exa-ct description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. K

My present invention relates to wall structures and is in the nature of a modification or refinement of the wall .structure disclosed and claimed in my pending application Serial Number 550,841, led of date April 8, 1922, and entitled Furnace walls. Generally stated, the invention consists of the novel construction, arrangement and combinations of parts hereinafter described and defined in the claims.

This improved wal as in the Wall of above identified pending application, the complete wall structure, when designed as an outside wall, is made up of what may be designated as a permanent masonry outer wall and .a replaceable high refractory masonry inner wall. struction, the permanent outer wall is preferably faced with fire brick or bricks, which become a relatively permanent part of saidv outer wall.

Attention is first called to the construction illustrated in Figs. 1 to 8, inclusive, wherein the outer common brick 24 of the permanent outer wall may be laid in any desired number of horizontal layers and is faced with lire brick 25. built into the permanent outer wall and preferably extend completely through the further. modified con-y Sill-forming blocks 26 are In the preferred conl .said outer wall rbricks 27 placed one on top of the other.

The bricks 27 that form these pilasters, at their vertical ed s, are tapered toward the outer surface o Athe permanent wall and fit against the tapered edges of the sill blocks 26, so that the latter are limited in their inl and lintels form,

ward movement,that is, are positively prevented from being removed by inward move` ment but are capable of being moved by outward movement. The pllasters are 'I v. cappedV by lintels 28 in the form of large fire tiles or blocks seated on said columns and forming a horizontal layer, which preferably does not extend back through the common brick 'masonry of the said permanent outer wall. The cooperating sill blocks, pilasters tend back 'into but not through. Athe com-` mon brick mason 2a. In the construction here illustrated, t e sill-forming blocks 26,

' at the bottoms of the pockets, are formed 30 with raised beads 29, preferably curved in cross-sectionl and located considerabl inward of the inner ends of said sill b ocks.

The replaceable inner wall should be made up entirely of high refractory bricks or tiles and, as shown is made up chiefly of hori zontal belts oi re bricks 30, but betweenA these belts are interposed horizontal layers of shelf-forming blocks or tiles ,31 that preferably have 'the same horizontal widthv as and to the backs of the manent outer wall. To cause them to interforming tiles 31 are the inner edge portions of the pockets of the permanent wall vstructure and, hence, are adapted to fit into said pockets and to be seated on the sill blocks 26. These shelfpreferably long enough to extend through the replaceable inner wall pockets in the perlock fwith the sill blocks,- said blocks 31 are vformed on their under-surfaces with transverse lock grooves 31a of the same cross-section as the beads 29, so that they areA adapted to fit the latter. Key blocks 32, preferably i in the form of talpered fire bricks, arranged vpablo inner wall an in groups are. p aced on top of the shelformin'g. locks 31 and forced into the pockets and' against the beveled under-sur faces 28 of the lintels 28 and, when thus appermanent outer wall. L

:Spaces in the replaceable inner wall, between the shelf-forming blocks'31, are filled in by supplemental shelfforming tiles or blocks 33 that extend onl through said reabut against the in the inner face of the rpermanent outer wall, vertically spaced horizontal rows ofrectangular pockets that ex- ,oea

the said'tiles 31 andcompletely i Certain of the sill blocks 26 are arranged i in vertical rows that align with buckstays' 35, which latter, ias shown, upright steel channel beams placed back to back but slightly spaced, in the customary or an suitable wa and ufor anchorin sill, blocks direct y to said buckstays, preferably provide anchor rods 36 provided at their outerthreaded ends with nuts 37 and washers 38 and, at their inner ends, with downturned hook lugs 39. The sill blocks that are'aligned with the buckstays are formed in their upper surfaces with grooves 40 that terminate m depressed lock notches o1; pockets 41. When the rods 36 are turned, as shown in Fig. 4, they' may be inserted endwise through the grooves d() and then their lugs 39 can be turned downward into interlocking engagement with the notches 41. Then, when the nuts 37 are tightened, the sill blocks will be directly anchoredto the buckstays and the furnace will be Aindirectly anchored to said buckstays.Y

` When the shelf-forming blocks 31 are interlocked to the sill blocks, the latter will be positively interlocked in the wall so that they cannot possibly be removed by outward movement or otherwise. forming `blocks are removed from position, then it will be possible to remove the sill blocks by endwise movement in a direction are made up ofthese When the shelftoward the outer face of the Wall, but

this should .require the immediately overlyingv bricks of the permanent `outer wall first' to be removed. This makes possible the replacement of the sill blocks, if at anytime t ey should become damaged. The tapered` form above described is a convenient form foreventing the sill blocks from being .mov inward and for keepin the same interlocked in the permanent wal except by the manipulations above noted.

Fig. 1- illustrates very clearly the fact that any one or more of the bricks for blocks of the lreplaceable inner wall may be removed and replaced at will without disturbing certaln other bricks or blocks that have not been damaged. The removal of the shelfforming blocks requires only that the overlyin bricks-be removed therefrom and that the ey blocks 32 then be removed. f

Thesill-fonnin'g blocks and the fire bricks 27 that formthe pilasters. will very seldom requlre replacement, while the shelf-forming' blocks 31 ma very ik uently require .replacements` ence, p blocks will be shi ped in much larger uanjtlties than the si l-ormin blocks an the ablllty to compactly' pile 'th the said shelf-forming esame togetherA for shipment is, therefore, a very important matter. With the arrangement described and with other arrangements hereinafter illustrated, the said shelf forming blocks are formed with six flat surfaces without projections, but, in some instances, with indentations, and as they are rectangular 1n form, they may be piled together as closely as ordina bricks or other perfectly rectangular bloc and this reduces the cost of shipment and the liability of breakage of the blocks.

The construction illustrated in Figs. 9, 10 and 11 is like that illustrated in the views above described, with the following exceptions, to wit: the sill-forming blocks 26- are formed on their upper faces with approximately semi-,cylindrical bosses or perforations 42 that areengageable with reversely formed indentations 43 in the shelf-forming blocks 31. Also, the lintels 28 are not beveled at their under-surfaces and the key blocks 32a are not tapered but are of the ordinary brick form.

The construction illustrated in Fig. 12 is like that illustrated in Figs. 1 to 7, inclusive, except that the permanent outer wall and replaceable inner wall are spaced to form an a1r p 44 and the sill blocks 26b and -the shellorming blocks-31" have flat engaging surfaces. l f

The construction illustrated in Fig. 13 is like that illustrated in Fig. 12, except that the two walls are built close together, or without air space between them, and that the sill blocks 26@ and shelf-forming blocks 31c are interlocked by metallic anchors 45. These metallic anchors 45 have downturned lugs 46 and upturned lugs 47. The sill blocks 26c are formed with channels 48 that terminate in depressed extremities that receive the anchors 45 and their depending lugs 46, while the 'shelf-forming blocks 31 are formed with pockets 49 that receive the upturned lugs 47 of said metallic anchors.

The construction illustrated in Figs. 17, 18, 19 and 20 is like that illustrated in Fig. 13, except that the sill-forming blocks 26d and shelf-forming blocks 31d are formed, re-

spectively, with rectan lar pockets 50 that receive an anchoring brick or block 51, which positively` interlocks the .two blocks 26l and 31d together.

The constructlon illustrated in Figs. 21, 22 and 23 is like that illustrated in Fig. 13, except that the sill blocks 26 and shelflforming blocks 31, in addition to being inl terlocked by the metallic anchor 45, are further interlocked by ledges '52 and 53 formed, re ectively, on said blocks.
